Additional Notes
- The Volkswagen ID.4 E21 / E81 brake fluid capacity of 1.2 liters applies to the hydraulic brake system, which is the reservoir and line volume used during a standard service fill rather than a full system overhaul.
- The 24-month change interval is tied to normal use conditions, meaning regular driving without the elevated thermal or contamination stress associated with severe use classifications.
- Both the 58 kWh and AWD 77 kWh configurations share an identical 1.2-liter capacity, indicating no variation in hydraulic brake system volume between the single-motor and dual-motor drivetrain layouts.
- The 58 kWh variant carries a model year range of 2020-2024, while the AWD 77 kWh variant begins at 2021, reflecting a one-year offset in the introduction of the all-wheel-drive configuration.
- Despite the difference in battery capacity and drivetrain architecture between the two configurations, the 24-month brake fluid change interval remains consistent across both, with no deviation based on powertrain type.
